The complete question in the attached figure
we know that
[volume of a triangular prism]=[area triangular base]*[length]
[volume <span>of a triangular prism]=[(14.4*2.1)/2]*8.25
</span>[volume of a triangular prism]=124.74 mm³
the answer is 306
Answer:
C.
Step-by-step explanation:
Multiplying identical variables together is identical to adding the exponents of each.
In this case, you have three 
s. You can multiply these to create 
.
Now, you have 
.
Negative exponents mean that the base (b in this scenario) is on the opposite side of the fraction line.
Answer:
it's C
Step-by-step explanation:
you just need to make everything the opposite of the original equation.
Step-by-step explanation:
Equations:
Quantity:: d = n + 3
Value::: 10n + 5d = 615 cents
-------------------------------------------
Modify::
d - n = 3
d + 2n = 123
--------------------------------------------
Subtract and solve for "n"::
3n = 120
n = 40 (# of nickels)
d = n+3 = 43 (# of dimes)
